| FFF Compatibility | The pinout and package are identical because it uses the exact same silicon die in the same 8-SOIC package.Identical 8-SOIC dimensions and lead pitch (1.27mm).Identical electrical parameters, absolute maximum ratings, and feature sets. | Shares the identical pinout mapping but in a physically smaller package, requiring layout adjustments.Housed in a VSSOP-8 (MSOP-8) package instead of SOIC-8, which has a smaller body width and pitch.Electrically identical to the queried part. | ||
 AI Summary | LM3478MAX/NOPB by Texas Instruments: Boost, Flyback, SEPIC Regulator Positive Output Step-Up, Step-Up/Step-Down DC-DC Controller IC 8-SOIC. | This is the identical IC in the same SOIC-8 package, differing only in the packaging container from tape and reel to a tube. It offers perfect drop-in compatibility with no physical or electrical design changes needed.
| This is the same regulator from the same series, but packaged in the smaller VSSOP-8 (MSOP-8) form factor. It is electrically identical and shares the same pin assignments, but requires a board footprint layout change.
